Chitukuko malangizo ndi chiyembekezo madzi galasi mankhwala grouting zipangizo

Galasi lamadzi limagwiritsidwa ntchito ngati chomangira zinthu zakuthupi. Amatchedwanso pyrophorine. Ma silicates azitsulo zotere amapangidwa ndi kusungunuka kwa mchenga wa quartz ndi sodium, kapena potaziyamu, kapena lithiamu carbonate (kapena sulfate). Kapangidwe kake ka mankhwala ndi R2O•nSiO2•mH2O, R2O imatanthawuza ma oxide achitsulo amchere, monga Na2O, K2O, Li2O; n amatanthauza chiwerengero cha moles wa SiO2; m ndi chiwerengero cha timadontho-timadontho ta H2O yomwe ili nayo. Izi alkali zitsulo silicates kusungunuka m'madzi ndi hydrolyze kupanga sol. The Sol ili ndi katundu wabwino wa simenti. Chifukwa chake, imagwiritsidwa ntchito kwambiri ngati chomangira chazinthu zakuthupi m'makampani, chomwe chimagwiritsidwa ntchito kwambiri ngati chomangira chamakampani okanira, ndipo chimagwiritsidwa ntchito ngati accelerator ya konkire ya simenti pomanga, komanso imagwiritsidwanso ntchito kwambiri popanga mapepala ndi mafakitale a nsalu. Mayendedwe a chitukuko ndi chiyembekezo cha sodium silicate chemical grouting materials:

① Zipangizo zopangira ma Chemical grouting zimagwiritsidwa ntchito kwambiri muukadaulo wapansi panthaka, ndipo malo apansi panthaka ndi ovuta komanso osinthika, omwe amafunikira kupangidwa kwamitundu yosiyanasiyana ya zida zamagalasi amadzi zomwe zimagwiritsidwa ntchito bwino molingana ndi malo osiyanasiyana apansi panthaka.

Limodzi mwa matanthauzo ofunikira a kafukufuku watsopano wa sodium silicate slurry ndikuti wothandizila wamkulu wa sodium silicate slurry sangabweretse mavuto a chilengedwe kuwonjezera pa kuwononga zamchere, kotero posankha zowonjezera, m'pofunika kuganizira ngati ndi poizoni, poizoni. musanagwiritse ntchito slurry, kapena poizoni panthawi yogwiritsira ntchito, kapena poizoni pambuyo pomaliza ntchitoyo. Kuyang'ana zowonjezera zopanda poizoni za sodium silicate ndiye njira yopangira zinthu zatsopano za sodium silicate slurry.

③ Madzi galasi zamkati zamkati monga mankhwala grouting zakuthupi ali ndi mbiri yakale ntchito, koma mfundo yake kulimba mpaka pano, palibe mawu ofanana, kupanga madzi galasi zamkati zakuthupi latsopano, m'pofunika kuchita kafukufuku mozama. pamadzi galasi gel osakaniza makina.

(4) The polymerization ndi kuchiritsa ndondomeko ya sodium silicate slurry ndi njira yovuta kwambiri, ndipo pokha pokha pomvetsetsa mfundo ya kugwirizanitsa simenti tikhoza kupereka maziko ophunzirira nthawi ya gelation ya sodium silicate slurry.

Poyerekeza ndi zipangizo zina zopangira mankhwala, ubwino waukulu wa sodium silicate slurry ndi wotsika mtengo, ndipo kuipa kwake ndikuti mphamvu zake zophatikizana sizili bwino monga slurry wamankhwala, kotero mphamvu ya sodium silicate slurry kuti ifufuze zomwe zingatheke, imakhalanso tsogolo la zoyesayesa.

Kugwiritsa ntchito sodium silicate slurry pakali pano kumangokhala ntchito zosakhalitsa kapena zosakhalitsa, chifukwa kafukufuku wokhazikika ayenera kukhala wozama.

Kapangidwe kazinthu zosinthira magalasi amadzi, kuchokera pakusintha kamodzi kupita pakusintha kophatikiza, kuyesako kunatsimikizira kuti kugwiritsa ntchito zosinthira zophatikizika kuposa zosintha kamodzi nthawi zambiri zimakhala ndi magwiridwe antchito abwino kwambiri.
